(CNN) - Oregon Rep. David Wu said Thursday he will cast his superdelegate vote for Barack Obama.

"I think we are blessed to have two strong candidates for president," Wu said in a statement released by Obama's campaign. "I am endorsing Barack Obama for president today because I believe that he is best suited to turn the page on this sorry episode in American history. He and I both had the judgment to oppose the Iraq War from the very beginning.

Wu, a five term congressman, is one of the party's nearly 800 superdelegates who will ultimately decide who gets the Democratic presidential nomination. He is the second Oregon superdelegate to endorse Obama ahead of the state's May 20 primary - Rep. Earl Blumenauer endorsed the Illinois senator earlier in the year.

Clinton also has two Oregon superdelegates in her camp - Gov. Ted Kulongoski and Rep. Darlene Hooley.
